Tetrasodium EDTA, which actually stands for ethylenediaminetetraacetic acid, may also be referred to as edetate sodium, tetrasodium salt, tetrasodium edetate and many other terms used in many other industries.
The main property of tetrasodium EDTA is to decrease the reactivity of metal ions in a product, which makes it an important ingredient when making soaps. To make it simpler, this chemical is used to make hard water soft.

The difference in Use Between EDTA Disodium and Tetrasodium
There are two basic kinds of EDTA available to home crafters, so be sure to buy the correct type. Tetrasodium EDTA should be used in soap and other alkaline products. Disodium EDTA is the other kind of EDTA; it should only be used in neutral pH to slightly acidic products.
Tetrasodium EDTA is available in two forms: a powder that is about 99%min pure EDTA and liquid that is usually a solution of 40% EDTA in water. Either form can be used. The powder has dihydrate and the general tetrahydrate.
Tetrasodium EDTA Benefits in Soaps
EDTA offers two benefits when used in soap. It increases the shelf life of your soap by chelating (binding up) certain metals that can cause DOS (dreaded orange spots, also known as rancidity). EDTA also reduces the amount of sticky soap scum formed when lye soap is used in hard water.
EDTA and citrate do similar jobs, so if one does not appeal, then consider using the other. EDTA is arguably not as "crunchy" as citrate, so it is not the best choice for a "natural" soap. Both will function well to increase shelf life, but the consensus from informal discussions with other soapers is EDTA is more effective than citrate in reducing soap scum.
The products are packed in plastic woven bags lined with polyethene film bags or kraft paper bags, each bag has a net weight of 25.0kg, or according to the requirements of customers.
Marks
Each product package shall be provided with the firm and clear marks, including product name, specification, net content, batch number, production date and shelf-life or other info as customer required.
EDTA chelating agents are widely used in water treatment, dyeing, oil cleaning, etc.
Personal care &
skincare products
Binding to free metal ions and serves as a purifying agent and preservative.
Shampoos and soaps
Reducing the “hardness” (or presence of metal cations) in tap water so that other ingredients can work to cleanse more efficiently.
Laundry detergents
To soften water that comes into contact with it so the other active ingredients can cleanse better.
Textiles
Preventing the discolouring of dyed fabrics by removing harmful free metal ions and getting rid of residue left on industrial equipment.
Agriculture Fertilizers
EDTA metal salts like EDTA-Mn, EDTA-Fe and EDTA-Zn, etc are mainly used as foliar fertilizers, water-soluble fertilizers to supply trace elements for vegetables, crops, and fruits.
Foods
EDTA chelating agents are used for chelating metal ions, removing heavy metals of foods. EDTA metal salts e.g. Ca, Zn, Fe, are used for supplying micronutrients for human.
